Flatness tolerance is one of the most specified and least understood callouts in precision manufacturing. Flatness defines the zone a surface must stay within — the distance between two parallel planes bounding the surface. A 0.001″ flatness callout means the entire surface must fit inside a 0.001″ wide zone. It is not the same as…
